The present invention relates to an electrode assembly which comprises a previously formed gas discharge passage configured to communicate with the outside or a scheduled discharge passage, and thus gas generated inside the electrode assembly can be discharged out of the electrode assembly, and to a method for manufacturing the electrode assembly. According to the present invention, provided is an electrode assembly for a secondary battery, the electrode assembly comprising a positive electrode, a negative electrode, and a separator disposed between the positive electrode and the negative electrode, wherein the positive electrode is represented by chemical formula 1: Li_(1+a)Ni_bM_cMn_(2-(a+b+c))O_(4-z), where M is one or more selected from the group consisting of Ti, Co, Al, Cu, Fe, Mg, B, Cr, Zr, Zn, and other transition metals, and 0 <= a <= 0.1, 0.4<= b <= 0.6, 0 <= c <= 0.1, and 0 <= z <= 0.1 and includes lithium composite transition metal oxide, exhibiting an operating voltage in ...
